ABSTRACT
BACKGROUND:
Heightened attention allocation toward negative-valanced information and reduced attention allocation toward positive-valanced information represent viable targets for attention bias modification in major depressive disorder. Accordingly, we conducted a randomized controlled trial testing the efficacy of a novel gaze-contingent attention bias modification procedure for major depressive disorder.METHOD:
Sixty patients with major depressive disorder were randomly assigned to either eight training sessions of feedback-based gaze-contingent music reward therapy designed to divert patients' gaze toward positive over sad stimuli, or to a control condition which entailed eight sessions of gaze-noncontingent music. Clinician-rated and self-reported measures of depression, and proportion of dwell-time on sad faces, were assessed pretreatment, posttreatment, and at a 3-month follow-up.RESULTS:
Gaze-contingent music reward therapy produced a greater reduction in dwell-time on sad faces compared with the control condition, but it failed to generalize to novel faces. Both groups manifested similarly significant reductions in depression symptoms from pre- to posttreatment that were maintained at follow-up. Exploratory analyses suggest that first-episode patients may benefit more from this therapy than patients with a history of multiple episodes.CONCLUSIONS:
Gaze-contingent music reward therapy can modify attention biases in depression, but clear differential clinical effects did not emerge. Theoretical and practical implications are discussed.Palabras clave
